Add support for MyBatis framework

[steverao]

Is your feature request related to a problem? Please describe.

As a widely used persistence layer framework, MyBatis is widely used. Currently, the Span focus for database calls is only specific database types. For example, when using the mariadb client to call the database, the application layer will take a lot of time, but the specific database call will take very little time. It is not clear where the intermediate time is spent. , if the Mybatis can be supported, the time-consuming support of this type of framework can be clearly displayed to users. Will the community consider supporting it?

Are you sure that this extra time is spent in MyBatis? I would have thought that MyBatis itself doesn't do much and even if you create spans for it they'd not be much different from the underlying jdbc spans.

I did a preliminary implementation and found that this time-consuming process is actually much more time-consuming than underlying JDBC. For a simple application, the overall time consumption of Mybatis is about 2 times that of pure JDBC. The result are as follows:

If we support relevant span, users will have a complete global perspective, which includes the connection pool acquisition time and database statement execution time, which can help users to better understand the complete time-consuming of their database-related operations.

Please assign it to me, I will complete it soon.
